Also make sure you have cleared system cach after any update. In addition, please post your battery stats so we can see if there is a rogue app/apps causing the issue. Settings> Battery & Device Care> battery. click on graph and post a screenshot of the app usage.
This is 2 months old phone and haven't got any update yet. Also i have already done wipe cache partition.
There are no apps under Battery & Device care as I have not opened any apps.
Is it because S21 has plastic back so heat is absorbed rather than dissipation?
Just open settings on phone and browse through them. Phone temperature above 35.0 C in 5 min
25 C room temp
I have bought directly from samsung and can ask for repair as its only 2 months old phone. My phone temp goes down to 29 and stays there if phone idle and screen off but if i start using it goes above 35 easily within 5-10 min.
What is your phone's ideal temp ?
And till what level temperature goes when you use it normally for 5-10 min?
